Is your roof Santa-Safe?

Some maintenance tasks are common to all types of roof; others are specific to the particular roof type. Some tasks will need to be completed more often if you live close to the sea or in a geothermal area. Check with the manufacturer of your roof for specific maintenance requirements. Once a year you should have your roof cladding, chimneys and flashings checked by a reliable roofing contractor or builder.

Build-up of salts and dirt

This encourages rust on steel & galvanized iron roofs, and moss and lichen on tiles. If you live within a couple of kms from the seafront, you will have salt deposits in your gutters and areas of roof.  If you live in a flight landing corridor e.g.. Manukau and environs or Hobsonville/Herald Island and parts of North Shore, roofs will have darker deposits from aviation fuel. Regular annual or 2 yearly cleaning by a professional company will keep the roof fresh looking and clear of buildups that mask deteriorating surfaces.

Block off any gaps where birds can nest (after the fledglings have flown if you have already found them nesting!)

Damaged/unstable TV aerial or receiver dish

With the recent change to digital television in Auckland, many people will have had to replace aerials or have satellite dishes installed.   Generally installers are careful not to damage roofs however it is wise to have your roof checked.   Are there dents in coated metal tiles?  Have they left any unsealed screw holes upon removal of of aerial fittings that will allow water ingress?   Don’t wait to find out when the roof leaks next Autumn, or in a sudden summer storm.

Call Dwell to refer a competent inspector.

Chimneys

Concrete:  Check Mortar on concrete & brick chimneys (keep in mind that we have had several tremors in parts  Auckland in the past year) look for cracks, crumbling mortar and use a plumb-line to check the chimney is still vertically ‘in line’.

Metal:  Check for corrosion and lifted flashings around rooflines at the joints with the house and along the ridge lines.

Corrosion of flue pipe, cowl or fastenings is another common issue and could be due to a buildup of combustion deposits or trapped and ponding water.

Chimney cleaning:  T o keep your House Insurance Policy current you must have your chimney cleaned and inspected by a registered chimney sweep annually.    

Lifted or dislodged flashings

Flashings protect vulnerable areas of the roof – joints.  If they fail they affect the weather tightness of the roof allowing water to get into your home.  Flashings are usually damaged by people – replacing tiles, walking on the roof, cleaning roughly etc.

The condition of your roof is something that should be checked regularly.  How long since your roof was inspected?
